Radon in dwellings
• Commission Recommendation from 1990on indoor exposure to radon(90/143/Euratom)
• Council Directive from 1996 on BasicSafety Standards (96/29/Euratom): radon indwellings is not included in the scope of theBSS

EUROPEAN COMMISSION 5
EC Recommendation (90/143/Euratom)
• Establish a system for reducing anyexposure to indoor radon concentrations.
• Apply principles of optimisation.• Decisions should be made on annually-
averaged measurements• Develop criteria for identifying regions,
sites and building characteristics likely tocause high indoor radon levels
![Page 6: European Commission approach with regard to radonold.iss.it/binary/tesa/cont/4-European Commission (Asa Wiklund... · 400 Bq/m3 •Construction design level for new buildings –](https://reader030.fdocuments.in/reader030/viewer/2022013014/5ae8481b7f8b9aee078f552c/html5/thumbnails/6.jpg)
EUROPEAN COMMISSION 6
EC Recommendation (90/143/Euratom)
• Reference level for existing buildings– Annual average radon gas concentration of
400 Bq/m3
• Construction design level for new buildings– Annual average radon gas concentration of
200 Bq/m3
![Page 7: European Commission approach with regard to radonold.iss.it/binary/tesa/cont/4-European Commission (Asa Wiklund... · 400 Bq/m3 •Construction design level for new buildings –](https://reader030.fdocuments.in/reader030/viewer/2022013014/5ae8481b7f8b9aee078f552c/html5/thumbnails/7.jpg)
EUROPEAN COMMISSION 7
Radon at workplaces
• Council Directive from 1996 on Basic SafetyStandards (96/29/Euratom), Title VII– Addresses work activities which may lead to significant
increases in exposure of workers or of members of thepublic due to natural radiation sources
– MS shall identify work activities of concern, inparticular those with exposures to thoron or radonprogenies
– For such activities MS shall require the setting-up ofmeans for monitoring and as necessary apply otherrelevant parts of BSS
![Page 8: European Commission approach with regard to radonold.iss.it/binary/tesa/cont/4-European Commission (Asa Wiklund... · 400 Bq/m3 •Construction design level for new buildings –](https://reader030.fdocuments.in/reader030/viewer/2022013014/5ae8481b7f8b9aee078f552c/html5/thumbnails/8.jpg)
EUROPEAN COMMISSION 8
EC RP 88 (1997): Recommendations forimplementation of Title VII
• A system is required which concentrates on highestexposure and where actions are most likely to be effective.
• Surveys of radon exposure in different types of workplaces• Action levels for radon: 500 – 1000 Bq/m3
• When radon concentrations remain above the Action levelthe principles of BSS should apply (controlled areas,monitoring and dose limits)
• Information and advice to employers on remedial actions
![Page 9: European Commission approach with regard to radonold.iss.it/binary/tesa/cont/4-European Commission (Asa Wiklund... · 400 Bq/m3 •Construction design level for new buildings –](https://reader030.fdocuments.in/reader030/viewer/2022013014/5ae8481b7f8b9aee078f552c/html5/thumbnails/9.jpg)
EUROPEAN COMMISSION 9
EC RP 95 (1999): Reference levels forworkplaces with naturally occuring
radionuclides
• Offers a technique for screening and categorisingrelevant NORM industries based on dose criteria
• Introduces a graded approach• Converts doses to activity concentrations using
different pathways and exposure situations• Inhalation of radon is one exposure pathway
![Page 10: European Commission approach with regard to radonold.iss.it/binary/tesa/cont/4-European Commission (Asa Wiklund... · 400 Bq/m3 •Construction design level for new buildings –](https://reader030.fdocuments.in/reader030/viewer/2022013014/5ae8481b7f8b9aee078f552c/html5/thumbnails/10.jpg)
EUROPEAN COMMISSION 10
Radon in drinking water
• Council Directive on the quality of waterfor human consumption (98/83/EC): radonand its decay products are excluded
• EC Recommendation on radon in drinkingwater (2001/928/Euratom)
![Page 11: European Commission approach with regard to radonold.iss.it/binary/tesa/cont/4-European Commission (Asa Wiklund... · 400 Bq/m3 •Construction design level for new buildings –](https://reader030.fdocuments.in/reader030/viewer/2022013014/5ae8481b7f8b9aee078f552c/html5/thumbnails/11.jpg)
EUROPEAN COMMISSION 11
EC Recommendation on drinkingwater (2001/928/Euratom)
• Natural mineral waters (Dir 80/777/EC) andwaters as medical products (Dir 65/65/EC) areexcluded from the Recommendation
• Representative surveys should be undertaken todetermine exposures by radon in domesticdrinking water supplies
• Reference to BSS Title VII for protection ofworkers in establishments where radon may bereleased from water to indoor air (waterworks,spas, swimming pools, etc).
![Page 12: European Commission approach with regard to radonold.iss.it/binary/tesa/cont/4-European Commission (Asa Wiklund... · 400 Bq/m3 •Construction design level for new buildings –](https://reader030.fdocuments.in/reader030/viewer/2022013014/5ae8481b7f8b9aee078f552c/html5/thumbnails/12.jpg)
EUROPEAN COMMISSION 12
EC Recommendation on drinkingwater (2001/928/Euratom)
• Public or commercial drinking water supplies:– Reference level for radon: 100 Bq/l– Reference level for Po-210: 0.1 Bq/l– Reference level for Pb-210: 0.2 Bq/l– Above 1000 Bq/l for radon, remedial action is always
justified.• Individual water supplies:
– Reference level for radon: 1000 Bq/l

EUROPEAN COMMISSION 13
Radon in building materials• Council Directive on construction products (89/196/EEC):
no specific guidance on radon but states that constructionworks must be designed and built in such a way that theemission of dangerous radiation will not be a health threatto the occupants or neighbours.
• EU BSS Title VII• EC RP 112 (1999) Radiological protection principles
concerning the natural radioactivity of building materials• EC RP 96 (1997) Enhanced radioactivity of building
materials – background report to RP 112
![Page 14: European Commission approach with regard to radonold.iss.it/binary/tesa/cont/4-European Commission (Asa Wiklund... · 400 Bq/m3 •Construction design level for new buildings –](https://reader030.fdocuments.in/reader030/viewer/2022013014/5ae8481b7f8b9aee078f552c/html5/thumbnails/14.jpg)
EUROPEAN COMMISSION 14
Radon in building materials
• RP 96 and 112 focus on external radiation• RP 112: ”When gamma doses are limited to
levels below 1mSv/y, the 226Raconcentrations in the materials are limited,in practice, to levels which are unlikely tocause indoor radon concentrationsexceeding … (200 Bq/m3).”

measurements and remedial actions– Criteria for delimitation of radon prone areas– Criteria for identification of buildings of concern– Criteria for accreditation of measurement and
remediation services

EUROPEAN COMMISSION 19
Proposal from WP Natural Sources
• Action plan (continued):– Strategy for conducting surveys of indoor radon
concentrations– Types of workplaces where measurements are needed– Methods and tools for remedial action– The basis for defining reference levels– Schedules for audits/reviews of action plan– Strategy for increasing public awareness and informing
decision makers of the risk of radon and its synergismwith smoking
